I also feel ETH will never overtake BTC. Some drastic measures would have to be taken in order for this to happen. ETH would have to improve its network drastically and adopt new tech like side chains and other measures that would allow other Dapps to run on the network without bogging it down.
I am a ETH long holder so I would love to see ETH pop, but, realistically I feel BTC will be on top for the foreseeable future.
